Introduction

OEM No.: WG9925522112

This is an OEM-standard heavy-duty chassis component specially designed for SINOTRUK heavy-duty trucks, fully compatible with HOWO, T7H, SITRAK and other mainstream series models. As a core fixing part of the front leaf spring suspension system, it is responsible for stably supporting and fixing the rear end of the front spring, bearing vehicle load and buffering road vibration impact. It maintains the stable structure of the front suspension system, effectively solving common chassis faults such as spring shaking, support loosening, abnormal noise and structural offset. Manufactured strictly in accordance with original factory process standards, it features precise mounting dimensions and 100% interchangeability with original parts. Widely applied to SINOTRUK tractors, dump trucks and engineering heavy trucks, it is an essential durable replacement part for global heavy truck aftermarket chassis maintenance.

Key Features

✅ 1. Exact OEM Matching, Direct Plug-and-Play Replacement

Produced strictly following the original OEM specification WG9925522112. All mounting hole positions, bending radian, thickness and assembly tolerance are completely consistent with original factory standards. No cutting, drilling or modification is required during installation, supporting fast and accurate replacement. It perfectly fits the front leaf spring and chassis assembly without installation deviation or loose fitting.

✅ 2. High-Strength Casting, Super Load-Bearing Capacity

Adopts high-density reinforced cast iron material with integral one-piece casting forming process. The bracket body features high overall rigidity, uniform stress distribution and strong compression and torsion resistance. It can stably bear heavy vehicle load and long-term chassis tension, effectively avoiding bending, deformation and fracture caused by heavy-load driving and road impact, ensuring stable support of the front suspension system.

✅ 3. Excellent Vibration Resistance & Structural Stability

Optimized structural stress design effectively disperses high-frequency vibration and instantaneous impact generated by bumpy roads and heavy-load climbing. It firmly fixes the rear end of the front spring, eliminates suspension shaking and chassis abnormal noise, maintains accurate suspension positioning, and prevents tire deviation and uneven wear caused by suspension displacement, improving overall vehicle driving stability.

✅ 4. Anti-Rust & Anti-Corrosion, Long Service Lifespan

The surface adopts professional anti-rust paint spraying and anti-oxidation treatment process, which can effectively isolate rainwater, sediment, humid air and road corrosive substances. It avoids rusting, peeling and metal oxidation of the bracket body, maintains long-term structural integrity and firmness, and greatly reduces frequent chassis maintenance and replacement costs for fleets.

✅ 5. Adaptable to Harsh Complex Working Conditions

With outstanding structural fatigue resistance and impact resistance, the bracket is specially optimized for heavy-duty working scenarios. It can operate stably for a long time in dusty mining areas, muddy bumpy roads and tropical humid environments, resisting continuous vibration and alternating load damage. It has ultra-low failure rate and strong environmental adaptability, fully meeting the rigorous operation needs of engineering and logistics fleets.

✅ 6. Strict Quality Inspection & High Cost Performance

Each front spring rear bracket passes strict dimensional inspection, structural pressure test and surface quality detection before delivery to ensure stable and reliable quality. With factory direct sales advantages and sufficient spot inventory, it supports sample trial orders and large batch wholesale, providing cost-effective and stable chassis spare parts supply for global repair shops, dealers and large fleets.
